Splash Shield Removal

  1. Start by parking your car in a flat level area. You’ll need to be able to work both under and above the car at times.


  2. Jack your car up and safely support it, or use a lift if you’re a baller.


  3. Using your trim tool remove the 5 trim clips across the front of the splash guard. This is done by pulling out the center until it stops, then popping the outside body out of the plastic shield.

     



  4. Remove the two 12mm bolts at the front.



  5. in front of each wheel, remove the trim clip near the tow hook, then the two on the wheel side, the top one is about halfway up the wheel well.

     

     

     



  6. Remove the two small plastic clips from the splash guard that goes to the metal skid plate on each side as well as two in the front.

     

     



  7. The splashguard should now drop out.




Stock Intake Removal

  1. At the top of the car, undo the hose clamp hosing the factory tube to the airbox using a screwdriver or 7mm socket.



  2. Moving under the car, pop the two clips at the front of the wheel well cover out as well as the 10mm bolt, this should give a little better access to the intake.

     



  3. With that pulled out of the way a little, remove the 10mm bolt holding the intake to the frame of the car. You can unbolt the bracket from the body as you won’t need the bracket wtih the new piece.

     



  4. Now undo the hose clamp to the turbo, and pull the whole tube out of the car.

     

     




COBB Intake Tube Installation

  1. Start by pre-assembling the couplers on the pipe in the orientation shown. Secure the couplers using the provided hose clamps.

    1. The pipe has two bends, one is oriented parallel to the main 90 degree bend in the pipe and are both going to follow along the floor (as seen towards the bottom right). This will go towards the turbo inlet. The other bend is perpindicular to those bends going towards the floor and lifting the pipe up. This goes towards the intake and can be seen in the top left in this picture.



    2. The 90 degree coupler will attach to the bend perpindicular to the 90, with the cobb logo facing away from the intake tube, and on the end that will attach to the intake box. Pre-install with one of the smaller clamps on the intake tube side, and the larger hose clamp on the side with the cobb logo. Do not tighten them yet.

       

    3. The 50 degree coupler can get installed on the opposite end with the cobb logo again on the end away from the intake tube. Pre-install the remaining two small hose clamps onto this coupler.



  2. Work the new COBB pipe into the car, it should match the orientation of the stock intake going up to the airbox and the turbo inlet.

     

     

     



    1. If you’re struggling to get the pipe in place, you can take the 90 degree coupler off and install it onto the airbox and then slip the pipe into it. Additionally through unplugging the MAF sensor, and undoing the two metal clips holding the airbox lid on, you can remove the lid and have a bit more room for adjustment before getting things in place.

       



  3. Get the coupler in place over the intake airbox, leaving the clamps loose for now. (keep in mind that there is a small square to key the factory intake in place, the coupler should go right up against that but doesn’t need to go over it.



  4. Slip the other end over the turbo inlet, again leaving things loose for the moment.



  5. Now you’ll want to rotate some of the couplers around a small bit to make sure the intake tube is sitting in a good spot. You want to make sure it has clearance with the fender, as well as the fender lining.

     



  6. Once you’re happy with the clearance, go ahead and tighten down the hose clamps starting at the turbo inlet and working out towards the airbox.

     

     



  7. Reinstall the splash shield, then you’re all done! Go out and enjoy!
